HN doesn't seem like a very lucrative pool for scams like this one. You don't see many meh corporate development jobs posted here, which are they ones you can fake for months or years. Hard to do that when you're working daily with the founder or a smaller team.

Starting salaries around $70-$80K, senior salaries around $140K-$160K and “architects” around $175K.
This is in the Atlanta market where I use to live before I started working remotely and moved. I got this email from a recruiter there. It’s about the same in most major non west coast markets
